No - consider a simple example:  Suppose that the entropy of the universe
increases continuously (in accordance with current theory), but suppose
that each year it increases by half the amount that it did in the previous
year.  Then, in any arbitrary starting year, it increases by x, and the
following year it increases by x/2, and then x/4, and so forth.  If you
sum the infinite series, you get 2x, which is far short of infinity, so
an infinitely old universe could have a very finite entropy.
